Phialemonium Obovatum
''Phialemonium obovatum'' is a saprotrophic filamentous fungus able to cause opportunistic infections in humans with weakened immune systems. ''P. obovatum'' is widespread throughout the environment, occurring commonly in sewage, soil, air and water. Walter Gams and Michael McGinnis described the genus ''Phialemonium'' to accommodate species intermediate between the genera ''Acremonium'' and ''Phialophora.'' Currently, three species of ''Phialemonium'' are recognized of which ''P. obovatum'' is the only one to produce greenish colonies and obovate conidia. It has been investigated as one of several microfungi with potential use in the accelerated aging of wine. Growth and morphology In culture, colonies of ''P. obovatum'' begin as white or off-white in colour becoming pale green and centrally darkened with age. The green pigments diffuse into the growth medium ultimately becoming blackish-green in colour. Although the hyphae of the fungus are typically colourless (hyaline), the ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the " ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomyce ...

Pezizomycotina
Pezizomycotina make up most of the Ascomycota fungi and include most lichenized fungi too. Pezizomycotina contains the filamentous ascomycetes and is a subdivision of the Ascomycota (fungi that form their spores in a sac-like ''ascus''). It is more or less synonymous with the older taxon Euascomycota. These fungi reproduce by fission rather than budding and this subdivision includes almost all the ascus fungi that have fruiting bodies visible to the naked eye (exception: genus ''Neolecta'', which belongs to the Taphrinomycotina). See the taxobox for a list of the classes that make up the Pezizomycotina. The old class Loculoascomycetes (consisting of all the bitunicate Ascomycota) has been replaced by the two classes Eurotiomycetes and Dothideomycetes. The rest of the Pezizomycotina also include the previously defined hymenial groups Discomycetes (now Leotiomycetes) and Pyrenomycetes (Sordariomycetes). Some important groups in Pezizomycotina include: Pezizomycetes (the opercula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sordariomycetes
Sordariomycetes is a class of fungi in the subdivision Pezizomycotina (Ascomycota), consisting of 28 orders, 90 families, 1344 genera. Sordariomycetes is from the Latin sordes (filth) because some species grow in animal feces, though growth habits vary widely across the class. Sordariomycetes generally produce their asci in perithecial fruiting bodies. Sordariomycetes are also known as Pyrenomycetes, from the Greek πυρἠν - 'the stone of a fruit' - because of the usually somewhat tough texture of their tissue. Sordariomycetes possess great variability in morphology, growth form, and habitat. Most have perithecial (flask-shaped) fruiting bodies, but ascomata can be less frequently cleistothecial (like in the genera '' Anixiella'', ''Apodus'', '' Boothiella'', ''Thielavia'', '' Zopfiella''),. Fruiting bodies may be solitary or gregarious, superficial, or immersed within stromata or tissues of the substrates and can be light to bright or black. Members of this group can grow ...

Sordariales
The order Sordariales is one of the most diverse taxonomic groups within the Sordariomycetes (subdivision Pezizomycotina, division Ascomycota). Species in the order Sordariales have a broad range of ecological diversity, containing lignicolous, herbicolous and coprophilous taxa. Most Sordariales are saprobic, producing solitary perithecial ascomata. They are commonly found on dung or decaying plant matter. The order contains a number of ecologically important species, including the model filamentous fungal genera Podospora and Neurospora, as well as potentially industrial-relevant fungi, such as members of the Chaetomiaceae family, which often produce biologically active secondary metabolites. The order Sordariales furthermore contains the highest diversity of thermophilic fungal species, with isolates present in seven different genera. Families in the order Sordariales Recent phylogenetic studies have aimed to contribute to the natural classification of this order. The most ...

Cephalothecaceae
The Cephalothecaceae are a family of fungi in the class Sordariomycetes. The family was circumscribed in 1917 by Austrian naturalist Franz Xaver Rudolf von Höhnel. Species in this family are saprobic, often growing on rotten wood or on other fungi. They are known to be distributed in northern temperate In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth.

Saprophytic
Saprotrophic nutrition or lysotrophic nutrition is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed (dead or waste) organic matter. It occurs in saprotrophs, and is most often associated with fungi (for example ''Mucor'') and soil bacteria. Saprotrophic microscopic fungi are sometimes called saprobes; saprotrophic plants or bacterial flora are called saprophytes ( sapro- 'rotten material' + -phyte 'plant'), although it is now believed that all plants previously thought to be saprotrophic are in fact parasites of microscopic fungi or other plants. The process is most often facilitated through the active transport of such materials through endocytosis within the internal mycelium and its constituent hyphae. states the purpose of saprotrophs and their internal nutrition, as well as the main two types of fungi that are most often referred to, as well as describes, visually, the process of saprotrophic nutrition through a diagram of hy ...

Dematiaceous
“Black yeasts”, sometimes also black fungi, dematiaceous fungi, microcolonial fungi or meristematic fungi is a diverse group of slow-growing microfungi which reproduce mostly asexually (fungi imperfecti). Only few genera reproduce by budding cells, while in others hyphal or meristematic (isodiametric) reproduction is preponderant. Black yeasts share some distinctive characteristics, in particular a dark colouration ( melanisation) of their cell wall. Morphological plasticity, incrustation of the cell wall with melanins and presence of other protective substances like carotenoids and mycosporines represent passive physiological adaptations which enable black fungi to be highly resistant against environmental stresses. The term " polyextremotolerance" has been introduced to describe this phenotype, a good example of which is the species ''Aureobasidium pullulans''. Presence of 1,8-dihydroxynaphthalene melanin in the cell wall confers to the microfungi their characteristic oliva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Human Body Temperature
Normal human body-temperature (normothermia, euthermia) is the typical temperature range found in humans. The normal human body temperature range is typically stated as . Human body temperature varies. It depends on sex, age, time of day, exertion level, health status (such as illness and menstruation), what part of the body the measurement is taken at, state of consciousness (waking, sleeping, sedated), and emotions. Body temperature is kept in the normal range by thermoregulation, in which adjustment of temperature is triggered by the central nervous system. Methods of measurement Taking a person's temperature is an initial part of a full clinical examination. There are various types of medical thermometers, as well as sites used for measurement, including: * In the rectum (rectal temperature) * In the mouth (oral temperature) * Under the arm (axillary temperature) * In the ear (tympanic temperature) * On the skin of the forehead over the temporal artery * Using heat flux ...
